| Abstract: | The calculation of overall strength of shell and tube waste heat recovery boiler is complex and crucial for its design and application. The strength of the tubesheet and the tubesheet-tube joint is particularly important. A more system- atic and appropriate representation of the real structure of tubesheet, tube arrangement and tubesheet-tube joint is shown by constructing a finite element model of the overall boiler. The more detailed and accurate distributions of stress and strain are obtained. Based on this approach, the design and optimization of waste heat recovery boiler would become more reasonable and efficient. |
